64 Notes from the Physiological Laboratory 



at the end of respectively ten and thirty-two days 

 thereafter : 



Comparison of these weights exhibits curious and 

 apparently contradictory results, viz., that during 

 the first ten days the gain was greatest in the pigs 

 fed upon whole wheat bread, whereas at the end of 

 thirty-two days of such feeding the gain was most 

 pronounced in the pigs fed upon bread made from 

 wheat whose three outer coats had been removed. 

 The cause of this variation in results is not far to 

 seek. At the commencement of the experiments 

 the animals were small, and the food given was in 

 each case more than sufficient to replace the waste 

 in both the tissues and circulatory fluids. Even the 

 pair fed upon bread containing the innutritious and 

 waste-inducing bran, digested and absorbed suffi- 

 cient proteid matter to supply the needs of the 

 tissues, and normal growth was also favored by the
